To all whom it may cancem: v

Be it known that I, BARNEY GOLDMAN, a

citizen ofthe United States, residing atv New York, in the county of NewYork and State of New York, have invented new and useful Im rovements inSnow-Melting paratusno which the following is a speci cation.

This invention relates essentiall to an in the direction of travel todirect the flame toward a bank of snow.

Another object of the invention is to provide a scooping device operatedby the propelled snow melting truck, whereby the soft snow and refuse iselevated from the ground into a wagon trailer connected to the snowmelting device.

Another object of the invention is to provide a motor convenientlymounted on the truck frame adjacent to the combustible tank forpropelling the truck.

The invention resides in the novel combinations hereinafter describedand claimed, reference being made to the accompanying drawing in which:

Figure 1 represents a sectional side elevation of an apparatus embodyingthis invention.

Fig. 2 is an inverted plan view of the snow melting truck.

Fig. 3 is a transverse section taken along the line 3 3 of Fig. 1.

. In thel drawing is shown a truck including front and rear wheels 5each having an axle 6 secured by means of hangers 7 to the platform orframe 8 of thetruck. On the plat formis secured a motor 9 driven bygasolene or other fuel. The motor has a belt and pulley connectionv 10with a pulle 11 on the rear axle for propelling the vehicle. On theplatform alongside of the motor is mounted a tank 12 for generatingcarbid. A coil 13 is arranged below the platform and it is cennecte tothe tank by means of a feed plpe 14 having a-'valve 15 for controllingthe flow of' the gas from the tank to the coll.

From the bottom of the coil project a series of nozzles 16 havinginclined or an ular portions to ypoint in a direction in whic thevehicle is traveling. Arranged insideof the said coil is another coilsection 17, best seen in Fig. 2. The latter is connected to the mainpipe b means of a branch pipe 18 as indicated in y to govern the flow ofas to the inner coil. The inner coil has nozz es similar to nozzles onthe outer coil and pointing in the direction in which the vehicle ismoving.

It will be understood, from the foregoin that the outer and inner coilsare indepen ent of each other in view of the fact that ig. 3, providedwith a valve 19 when the valve 19 of the branch pipe is shut,

it will eliminate the inner coil without interfering with the outercoil. The valve controls the volume of gas from the tank to both coils.This arrangement permits one coil to be put out of action when desired,while the other coil can remain in action. Any number of the coilsections and nozzles can be provided and as shown the flame at the endof a nozzle is ydirected toward the pile of snow while the truck ismoving forward.

In order to prevent any heat from the nozzles striking the platform andthe wheels of the truck, a sheet of asbestos 20 is arranged between theplatform and the coils.

vThe sheet has side members 21 extending downwardly to prevent the flamefrom injuring the wheels and other bearings. The axles can also becovered with a non-conductor of heat 22 where they are exposed to theflame.

At the back of the snow melting truck is positioned a vertical carrierconsisting of an endless belt or chain 23 engaging an upper roller orsprocket 24 and a lower roller or sprocket 25. The sprocket 25 isrotated in the proper direction by a cross belt 26 in engagement with adrive pulley 27 mounted on the rear axle of the truck. The endless belthas secured to it a series of buckets 28 made to scroop up any soft snowor dirt left from the melting snow or ice, elevate it and drop it intothe body of a wagon 29 rolling behlnd the carrier. vThe frame 30 of thecarrier is fastened to the forward part of the wagon and the wagon ishooked by removable bars 31 to the truck. A brush 3.3 to sweep up theremainder of the dirt 1s mounted below the body and it is connected tothe rear wheel by a belt 34 to rotate it when the wagon is moving. Whenit is desired to use the melting apparatus without the trailer, thelatter can be removed by unliookin the bars. v

it will be understood that the truck ma be attached or hooked to thefront of a tro ley car, railroad train or automobile, and variouschanges may be made in the position of the heat generating means ordriving mechanism Without departing from the principle of thisinvention.

l claim:

l.. A snow melting apparatus comprising a truck having a frame, meansfor propelling the truck, a fuel tank mounted on the frame, a pluralityof coils connected to the tank secured to the frame, each coil beingindependent of the other, a main pipe connecting the coils with thetank, a branch pipe leading from the main pipe to coil, a valve on themain ipe for controlling the volume of fuel admitted to each coil, avalve controlling the flow of fuel from the main pipe to the branchpipe, and a series of burner tubes projecting downwardly from the coils.

2. A snow melting apparatus comprising a truck having a frame, a fuelgenerator mounted on the frame, a plurality of coils connected to thegenerator arranged under the frame, each coil being independent of theother, means for controlling the volume `of fuel admitted to each coil,a valve for shutting oil one of the coils, and a series of nozzlesprojecting downwardly from the coils with angular portions to point in adirection of the travel of the truck.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
